Electrochemical Method for Removing Pollutants from Water

When removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. A new method was developed that could provide...

NASA's Langley Research Center has developed a novel polymer material that can be utilized as a real-time structural health monitoring sensor. The material is...

Researchers use fluorescent imaging to locate proteins and other molecules in cells and tissues by tagging the molecules with dyes that glow under certain kinds of light — the...

NASA Langley Research Center has developed technology to increase the adhesive strength between shape memory polymer composites (SMPs) and metal alloys. Shape...

Briefs: Communications
Personal Annunciation Device (PAD)

Many industrial and commercial plants, government and private research facilities, and industrial facilities perform potentially dangerous processes. Automated warning and alarm systems alert personnel to...

Briefs: Test & Measurement
Decoupled Ranging and Orientation Inversions Enable Linear and Fast Long-Range Non-Line-of-Sight Positioning

The wireless radio positioning or radiolocation problem is of great importance in society today. Existing radiolocation systems such as the Global Positioning System (GPS), Radio-Frequency Identification (RFID) systems, and Ultra...

Briefs: Aerospace
Calibration and Synchronization of Micro-Air-Vehicle Autopilots

Conventional calibration of an inertial measurement unit (IMU) through open-loop data collection includes typical flight simulator systems that provide processed stimuli to emulate real-life flight conditions. Other solutions involve testing inertial measurement devices on a...
